Tribehenin is a blend of skin-plumping glycerin and a gentle fatty acid known as behenic acid that helps prevent moisture loss. It is used to care for the skin, making it a useful additive in moisturizing creams and lotions. It can be plant derived (from coconut or palm oil) or synthetic.
In its crude form, tribehenin is a cream-colored solid. The independent Cosmetic Ingredient Review panel has found tribehenin to be non-sensitizing and determined that it is safe as used in cosmetics. Typical usage levels range from 0.5-12%, depending on form needs and aesthetic goals.
